Interstate Business Route 40

Eastbound Interstate 40 approaches Exit 285, Junction Business Loop I-40/Hopi Drive east, U.S. 180 southeast to St. Johns, and Arizona 77 south to Snowflake and Show Low. Photo taken 07/13/08.

Interstate 40 has 31 actively signed business loops, including the Winston-Salem business loop freeway. In addition, it has one decommissioned business loop and a few other potential future business loops that are currently signed as business U.S. routes.

Location Status Description
CALIFORNIA
Needles Active Listed in the 1991 California State Signing Log, this business route follows Old U.S. 66-95 (National Trails Highway) from west to east via River Road, North Street, Broadway, Acoma Street, and Front Street. The route remains signed as of March 2013. This business route also provides a connection to the north section of Arizona 95 en route to Bullhead City, which is not connected with the southern portion of the route.
See California @ AARoads - Business Loop Interstate 40 - Needles for the route guide.
ARIZONA
Kingman Decommissioned/Remnant Signage This business route used to follow Historic U.S. 66 between Exits 48 and 53 via Andy Devine Drive through the city of Kingman. On May 30, 2003, Business Loop I-40 through Kingman was decommissioned with approval by AASHTO in order to transfer maintenance of the highway from the state of Arizona to the city of Kingman. The route is now signed solely with Historic U.S. 66 shields, with occasional business loop shields. Generally, Arizona DOT does not permit non-state maintained routes to serve as officially signed business loops.
See Arizona @ AARoads - Business Loop Interstate 40 for photos of the former Kingman Business Loop.
Seligman Active Business Loop I-40 in Seligman follows Historic U.S. 66 between Exits 121 and 123.
Ash Fork Active This is Historic U.S. 66 and Old U.S. 89 between Exits 144 and 146. Notice how it's "old" U.S. 89 and "historic" U.S. 66.
Williams Active Historic U.S. Route 66 between Exits 163 and 165.
Flagstaff Active Multiplex heaven! Historic Route U.S. 66, Business Loop I-40, U.S. 180, Old U.S. 89, Arizona 89A, and Interstate 17 signs are everywhere along the main street called Route 66. I've been here, and I still can't tell you exactly where the southern end to U.S. 89 is located, but I can tell you which roads will take you to Interstate 40 and Interstate 17. Business Loop I-40 leaves Interstate 40 at Exit 191 and returns at Exit 201.
See Arizona @ AARoads - Business Loop Interstate 40 for photos of the Flagstaff Business Loop.
Winslow (LOOP) Active "I was standing on a corner in Winslow, Arizona, such a fine sight to see..." The Eagles (and Jackson Browne) probably sung (and wrote) about a corner that was Historic U.S. 66 and is now Business Loop I-40. This business connection is between Exits 252 and 255. The western end of Business Loop I-40 connects to Business Spur I-40 (see next entry).
Winslow (SPUR) Active Winslow also has a Business Spur I-40 that is mostly unsigned. According to Alan Hamilton, the Business Spur I-40 in Winslow is actually marked, but only at the end away from the interstate. It doesn't connect to anything in particular. The railroad bridge was not part of old U.S. 66. It was built in 1975, about the same time the mainline Interstate 40 was built. Old U.S. 66 followed the same route as Interstate 40; it didn't cross the railroad here. The Business Spur designation does make it the state's repsonsibility, rather than Navajo County. It goes west from Interstate 40, Exit 252. East of Exit 252 is the conventional business loop (see entry above).
See Arizona @ AARoads - Business Loop Interstate 40 for photos of the Kingman Business Spur and former Kingman Business Loop.
Joseph City Active Business Loop I-40 in Joseph City follows Historic U.S. 66 between Exits 274 and 277.
Holbrook Active Between Exits 285 and 286, this business route follows Hopi Street and Navajo Boulevard via old U.S. 66.
NEW MEXICO
Gallup Active This business route serves Gallup between Interstate 40 Exits 16 and 26, with the exits signed "Business Loop I-40, West and East Gallup." Gallup is another city along Historic U.S. 66 and is the southern terminus to U.S. 491 (formerly designated as U.S. 666 until AASHTO approved its renumbering on May 30, 2003).
Grants Active This business route follows Historic U.S. 66 through the city of Grants between Exits 81 and 85.
Albuquerque Decommissioned/ Remnant Signage Back in the 1970s-1980s, when U.S. 66 was still designated through Albuquerque, Central Avenue was also signed as Business Loop I-40. Once U.S. 66 was decommissioned in 1985, the residual route was left as Business Loop I-40. However, the business route is not signed from either direction on mainline Interstate 40. However, as of July 2008, the business loop signage was found along Central Avenue paired with U.S. 66 in a green guide sign. Several instances of this kind of signage is still present in and around downtown Alburquerque.
See New Mexico @ AARoads - Historic U.S. 66 - Albuquerque for photos of the former Albuquerque Business Loop along old U.S. 66.

Tucumcari Active The Tucumcari business route follows Historic U.S. 66 between Exits 325 and 329 via Tucumcari Boulevard. The loop is also signed as U.S. 54.
TEXAS
Glenrio Active Business Spur I-40A connects Interstate 40 to Historic U.S. 66 at Exit 0, which is very close to the Texas-New Mexico State Line. The Exit Authority lists this business spur in its 2000 guide. There is a local route from the west end of the spur (at the state line) that returns traffic to Interstate 40 on the New Mexico side.
Adrian Active Business Loop I-40B follows Historic U.S. 66 from Exit 22.
Vega Active Business Loop I-40C follows Historic U.S. 66 between Exits 34-37.
Amarillo Active Business Loop I-40D goes from Interstate 40 easterly and northwesterly via Amarillo, and then concurrent with U.S. 60 in Amarillo for approximately 10.8 miles, and then southeasterly to Interstate 40; a total distance of approximately 24.4 miles in Potter and Carson Counties. The business route follows Amarillo Boulevard, and the eastern half is cosigned with U.S. 60. The entire routing follows Historic U.S. 66.
Groom Active Business Loop I-40F follows Historic U.S. 66 between Exits 110 and 114.
McLean Active Business Loop I-40H follows Historic U.S. 66; between Exits 141 and 143.
Shamrock Active Business Loop I-40J follows Historic U.S. 66 between Exits 161 and 164.
OKLAHOMA
Erick Active The Erick business route follows a four-lane boulevard (a portion of which is a former U.S. 66 expressway) through the small Oklahoma town of Erick. This turns into a full-fledged expressway has it heads east. This business route is also Historic U.S. 66 between Exits 5 and 11.
Sayre Active The Sayre business route follows Fourth Street (Historic U.S. 66) between Exits 20 and 25.
Elk City Active The Elk City business route follows Historic U.S. 66 between Exits 32 and 41.

Weatherford Active The Weatherford business route follows Historic U.S. 66 between Exits 80 and 82.
El Reno Active Business Loop I-40 follows Historic U.S. 66 between Interstate 40 Exits 119 and 125. It connects with Oklahoma 66 at eastern end.
Henryetta Active This business route follows Historic U.S. 266 between Exits 238 and 240; it is also signed as Business U.S. 62-75. Thanks to David Backlin for information on this loop.
Sallisaw Active Business Loop I-40 in Sallisaw follows U.S. 59 (between Exits 307 to 308) and U.S. 64. This is the final business loop along Interstate 40 west of the Mississippi River.
TENNESSEE
Memphis Not a Business Loop Currently, there is no route number for Sam Cooper Boulevard, but this could make sense as a business spur or loop (perhaps with the western return to Interstate 40 via existing U.S. highways). Sam Cooper Boulevard is a city of Memphis road, not a state highway. Originally, Sam Cooper Boulevard was to be Interstate 40 through the heart of Memphis. Only parts of the planned Interstate were built. There had been discussion back when the transfer of authority was made to sign it as Business Route I-40, Interstate 140, or U.S. 64-70-79, but it was to no avail.
NORTH CAROLINA
Winston-Salem Active This Business Loop Freeway was approved by AASHTO on October 2, 1992, and remains signed to this day. It is partially cosigned with U.S. 158, U.S. 421, and North Carolina 150; mainline Interstate 40 is now routed to the south. This section of Interstate 40 was removed from the Interstate Highway System due to its substandard construction; however, some projects have improved the freeway including a.
Greensboro Decommissioned Business Loop I-40 in Greensboro was a brief designation for the original Interstate 40 freeway through Greensboro. The business loop, which was designated in February 2008, was an attempt to reroute Interstate 40 traffic around the downtown area. However, Business Loop I-40 was eliminated in September 2008 due to motorist confusion. Former Business Loop I-40 included a brief overlap with Business Loop I-85 (former Interstate 85 freeway) near downtown Greensboro. During the short time period when the business route was in use, both Interstate 40 and Interstate 85 were rerouted onto the Greensboro Bypass, which bypasses downtown to the south. This section of Interstate 40-85 was removed from the Interstate Highway System due to its substandard construction, including the infamous "Death Valley" segment. The Death Valley segment has been reconstructed and now meets Interstate standards again. The west end of the former business loop freeway almost connected with the Winston-Salem Business Loop I-40 freeway. The first part of the Greensboro Bypass, which carries Interstate 85 around the southeastern quadrant of the city, opened in January 2004. The Interstate 40 section of the bypass opened on February 21, 2008; the business route was signed on the old freeway alignment at the same time until its elimination in September 2008.
Raleigh Decommissioned The northern half of Interstate 440, the Raleigh beltway, was known as Business Loop I-40 until June 9, 1991. On that date, AASHTO approved the elimination of Business Loop I-40 in favor of newly formed Interstate 440. It's not clear to me what drove NCDOT to designate a beltway as a business loop - perhaps the only part of that name that was fitting was "loop." The beltway mostly avoided the downtown area, which is where most business loops go.

The only Interstate 40 business route in California is in Needles near the Colorado River. Business Loop I-40 follows Historic U.S. 66 (San Bernardino County Route 66) via Broadway Street, which makes several turns along its path including this turn at its intersection with River Road. Continue ahead for River Road north to Arizona 95 (not signed here, oddly) or turn right for Business Loop I-40, Historic U.S. 66, and San Bernardino County Route 66 east to downtown Needles. U.S. 95 is surprisingly signed here for the path to its southbound continuation. Business Loop I-40 reconnects with U.S. 95 at the other end of the loop, at Exit 144. Photo taken 03/24/13.
 
Still in Needles, Business Loop I-40 follows Historic U.S. 66 (San Bernardino County Route 66) via Broadway Street.

Turn right here for a fast return to Interstate 40, or proceed ahead for the continuation of the route into downtown Needles. Photo taken 03/24/13.
 
This Business Loop I-40 guide sign was formerly posted on Andy Devine Avenue in Kingman, Arizona. This loop was decommissioned in May 2003 and is no longer signed as a business loop. This route is now signed as Historic U.S. 66 with brown signs. Business Loops for Interstate 40 in Arizona generally follow former alignments of U.S. 66. Photo taken 10/24/03.
 
In Ash Fork, Business Loop I-40 follows Old U.S. 66 via the Park Avenue and Lewis Avenue one-way couplet between Exits 144 and 146.
